CA3100Y - 100Amp Circuit Breaker

CA3100Y - 100Amp Circuit Breaker

The CA3100Y is a 100 amp, 3 pole Type CA molded case circuit breaker commonly used in commercial and industrial electrical distribution equipment. If you're replacing an existing breaker, matching the original specifications is often the first priority. The CA3100Y combines a 100A rating, three-pole configuration, and a 10kA interrupting capacity at 240VAC, making it a suitable replacement for compatible Type CA installations.

This breaker features a non-interchangeable trip unit and comes with line-side lugs installed. Rated for operation in ambient temperatures up to 40°C (104°F), the CA3100Y is built for everyday service in working electrical systems.

For maintenance teams, electrical contractors, and facility managers, finding the right replacement breaker often comes down to the details.
